lUM BRELLA-FRAM E.

SPECIFICATION forming part of Letters Patent No. 416,658, dated December3, 1889.

l Application filed November 15, 1888. Serial No. 290,908. (No model.)

To a/ZZ whom, t may concern:

Be it known that I, JOHN WEEKs,a subject of the Queen of Great Britain,and aresident of Peckham, in the county of Surrey, in England, haveinvented certain new and useful Improvements in Frames for Umbrellas andthe Like, of which the following is a specification, reference being hadto the accompanying drawings.

These improvements refer to the ribs and stretchers, and especially tothe rib and stretcher joint of an umbrella-frame, and combine tomake theframe more compact when folded, While at the same time the strength andlightness are increased.

In the accompanying drawings, Figure 1 is a side view of the improvedform of rib at the stretcher-joint, and Fig. 2 a cross section. Fig. 3shows the geat before being bent, and Fig. et after being being bentinto shape ready to be applied to the rib. Fig. 5 is a crosssec tion ofthe geat. Fig. 6 is a side view, and Fig. 7 a cross-section through thestretcherjoint after the geat has been applied and bent over and therivet-holes made therein. Fig. 8 is a plan View of the stretcher. Fig. 9is a side View, Fig. 10 a cross-section of the rib and stretcher joint,and Fig. 11 a cross-section through rib and stretcher folded. Fig. 12 isa side View (in continuation, though broken in length, of Fig. 9) of riband stretcher at the place Where the rib enters a notch in therunnerlilange; and Fig. 13 is a cross section through the rib at thisplace.

At the stretcher-joint of a U-shaped rib A, I turn over toward theinside and iiatten down the sides of the rib, as shown at A', Figs. land 2, and I form the geat B, Fig. 3, with two correspondingly-shapedlugs B for containing the holes for the joint pin or rivet, so that Whenthe geat is iirst bent into the shape shown in Figs. 4 and 5 and lappedaround the rib at this place, and the lugs B folded inward, as shown inFigs. 6 and 7, the lugs B of the geat fill the hollow formed in eachside of the rib by the aforesaid turning over and flattening down of thesides of same. The geat is thus prevented from shifting endwise alongthe rib; or, instead of turning down the rib in this place, I merely cutout half-round notches therein; but this weakening of the rib might thennot be compensated for Sufficiently by the geat B.

If the rib, as shown at A2, Fig. 1, is bulged and the geat perforated atthis place, as shown at B2, Figs. 3, 4, 5, 6, 9, and 10, and asdescribed in my patent application filed in the United States PatentOffice on the 31st May, 1887, Serial No. 239,863, then the joint is Welldown in the hollow of the rib without loss of strength to the joint, therivet C not passing through the rib A, but through thegeat B, and thestretcher and the rib fold closely into each other without protuberanceai the joint, as shown at Figs. 9, 10, and 1l.

In connection with the rib and geat formed as described I may use anystretcher with three-pronged rib-joint end, but by preference the solidthree-pronged stretcher claimed in my aforesaid patent specification.This form of stretcher is by preference made of ribbon metal folded intothe required double- U section by rolling, but may also be madeotherwise,suc11 as by rolling out of the solid.

In Figs. S, 9, 10, and 11 is shown a threepronged stretcher made out ofone piece of ribbon metal by rolling. u

The rib where it lies in the notch formed in the edge of therunner-liange is, as shown at E, in Figs. 12 and 18, iiattened down, sothat the ribs will lie deeper in the said notches.

and the umbrella when folded will present a less bulky appearance atthis place. y

I have herein described and shown a U- shaped rib provided with a bulge,and I do not desire to claim this construction, broadly, herein,as itforms the subj ect-matter of claims in my application of patenthereiiibefore referred t0.

Having fully described my invention, what I desire to claim and secureby Letters Patent is 1. A trough-shaped umbrella-rib formed f IOOcavities at A and are adapted to receive the rivet C, which passesthrough the geat, but not through the rib, substantially as set forth.

3. The geat B, With lugs B B and hole B2, in combination with atrouglrshapecl rib A, with turned-down parts A and bulge A2,substantially as set forth.

4. A trough-shaped umbrella rib having turned-down stretcher-joint partsA a geat B, with turned-down lugs B and rivet C, and the(louble-U-shaped three-pronged stretcher D, made of ribbon metal andhaving a threepronged stretcher-joint end, substantially as set forth.

5. In an umbrella, the combination, with the runner, ofa trough-shapedrib having its lVitnesses:
